Can you please try to somehow concretize your milestone-plan with some dates?
I know, it is always hard to tell “when” in software-development but you once mentioned to hopefully reach milestone 0.6 in January 2014 and now it’s May and it doesn’t look anywhere near 0.6. Waiting for tasks and therefore 0.8 I am wondering if I have to get an in-between-solution for the next 2 months or for the next two years.
